Study Notes
Respiratory System
- Breathing is fundamental to life, representing the first and last dramatic moments of human experience.
- Respiration is necessary because most metabolic processes directly or indirectly require ATP.
- ATP production requires oxygen and generates carbon dioxide.
- The respiratory system primarily transports air to the lungs for gas exchange.
- Oxygen diffuses into the blood, and carbon dioxide diffuses out.
Main Function
- The respiratory system is a specialized organ system that provides oxygen to the blood and removes carbon dioxide.
- It has additional functions like smell and speech.
- It also regulates blood pressure and is involved in expelling abdominal contents.
Respiratory Tract
- Upper Respiratory Tract Parts:
- Nose
- Mouth
- Pharynx
- Larynx
- Lower Respiratory Tract Parts:
- Trachea
- Bronchi (right and left)
- Bronchioles
- Alveoli
- The respiratory system is a pathway for air that branches into the lungs, where gas exchange occurs.
Lungs
- They have three surfaces for ventilation:
- Diaphragmatic surface
- Costal surface
- Mediastinal surface
- The lung root contains structures like the main bronchus, blood vessels, and nerves.
Pleura
- The pleura is a two-layered membrane around the lungs.
- The visceral pleura directly covers the lungs.
- The parietal pleura lines the thoracic cavity.
- A fluid-filled space between the membranes reduces friction during breathing.
